One of the more common combustion reactions is the combustion of an alkane in the presence of oxygen.
A general strategy for balancing these combustion reactions is to first balance the carbon (C) atom, followed by the hydrogen atoms (H) and then then oxygen (O) atoms.
Remember: C H O
The combustion of alkanes in the presences of oxygen will produce carbon dioxide and water. Here is the reaction for the combustion of propane , an alkane containing 3 carbon atoms.
Here is the balanced equation for the combustion of propane , an alkane
containing 3 carbon atoms:
